After months of working hard to bring Replicant to the next upstream release, we are proud to announce the release of the Replicant 4.0 0001 images. This new release comes with support for both new devices, such as the Galaxy Nexus or the Galaxy S2 and devices that were already there in Replicant 2.3, like the Nexus S and the Galaxy S.
Aside from the new Ice Cream Sandwich user experience, that we tried to make as good as possible without any non-free blob, most devices have better hardware support than before, such as Galaxy S which now has working camera, or the global improvements that were made to make telephony more stable and reliable. Even though it's not perfect yet, we are proud of the result, that many of us use daily. If you encounter a particular problem with our software, do not hesitate to report the issue via our tracker, or give feedback when a problem was resolved.
We are indeed writing hundreds of lines of code to have more hardware supported and with a better state, replacing non-free components, step by step. Keep in mind that Replicant has a very small core team, we're just two people doing this on our free time: that means we can't work on every side of the project at the same time and have to make choices. This is why we will always welcome serious new contributors who'd like to get involved in the project.
You can download the images from the ReplicantImages page and find installation instructions as well as build guides on the Replicant wiki.
